Patient-Physician Sex Discordance and "Before Medically Advised" Discharge from Hospital: A Population-Based Retrospective Cohort Study.

BACKGROUND: Patient-physician sex discordance (when patient sex does not match physician sex) has been associated with reduced clinical rapport and adverse outcomes including post-operative mortality and unplanned hospital readmission. It remains unknown whether patient-physician sex discordance is associated with "before medically advised" hospital discharge (BMA discharge; commonly known as discharge "against medical advice"). OBJECTIVE: To evaluate whether patient-physician sex discordance is associated with BMA discharge. DESIGN: Retrospective cohort study using 15 years (2002-2017) of linked population-based administrative health data for all non-elective, non-obstetrical acute care hospitalizations from British Columbia, Canada. PARTICIPANTS: All individuals with eligible hospitalizations during study interval. MAIN MEASURES: Exposure: patient-physician sex discordance. OUTCOMES: BMA discharge (primary), 30-day hospital readmission or death (secondary). RESULTS: We identified 1,926,118 eligible index hospitalizations, 2.6% of which ended in BMA discharge. Among male patients, sex discordance was associated with BMA discharge (crude rate, 4.0% vs 2.9%; adjusted odds ratio [aOR] 1.08; 95%CI 1.03-1.14; p = 0.003). Among female patients, sex discordance was not associated with BMA discharge (crude rate, 2.0% vs 2.3%; aOR 1.02; 95%CI 0.96-1.08; p = 0.557). Compared to patient-physician sex discordance, younger patient age, prior substance use, and prior BMA discharge all had stronger associations with BMA discharge. CONCLUSIONS: Patient-physician sex discordance was associated with a small increase in BMA discharge among male patients. This finding may reflect communication gaps, differences in the care provided by male and female physicians, discriminatory attitudes among male patients, or residual confounding. Improved communication and better treatment of pain and opioid withdrawal may reduce BMA discharge.

A Call for Bigger Thinking and Meaningful Improvements in Health and Well-Being: Time to Move on From Small-Scale Changes.

Effective reforms to provinces' and territories' healthcare delivery systems are needed to generate meaningful changes in population-based health and well-being outcomes in Canada. These reforms include transformations that slow the decline of health and improve the quality of life - such as those relevant to long-term care and aged care - and are expansive enough to include prevention and health promotion.

The Eye-Opening Truth About Private Surgical Facilities in Canada.

This paper examines the contentious issue of using contracted surgical facilities (CSFs) for scheduled eye surgeries within Canada's publicly funded healthcare system. Despite the debate over the use of CSFs, there is a stark lack of Canadian-focused empirical evidence to guide policy decisions. This paper uses the Organisation for Economic Co-operation and Development's healthcare system performance conceptual model - access, quality and cost/expenditures - as a framework to explore the debates surrounding CSFs. It highlights the mixed evidence from international studies and proposes recommendations for policy makers to ensure equitable access, maintain high-quality care and achieve cost-effectiveness. The paper underscores the necessity for informed policy making supported by robust empirical research, stakeholder engagement and continuous policy evaluation to address the challenges posed by the integration of CSFs into Canada's healthcare landscape.

Preoperative depression and anxiety associated with younger age and receipt of immediate breast reconstruction.

BACKGROUND: As survivorship for breast cancer continues to improve, emphasis of care falls upon improving patients' quality of life. Understanding physical and mental health in the preoperative period is needed to aid surgical decision making and improve patient experience. METHODS: Consecutive patients awaiting total mastectomy (TM), TM with immediate breast reconstruction (IBR) and breast conserving surgery (BCS) were prospectively recruited. Scores for PHQ-9, GAD-7, Breast-Q, EQ5D(5L), PEG were collected preoperatively. Association was measured with multivariate analyses. RESULTS: 477 participants (374 BSC, 46 â€‹TM, 84 IBR) were included. Younger patients and those choosing IBR reported worse depression and anxiety symptoms. Clinical tumor features did not affect patient reported outcomes. Higher Breast-Q scores were seen with BCS and lower scores with TM. CONCLUSIONS: Patients scheduled for IBR and younger patients reported worse symptoms of depression and anxiety, regardless of clinical features. This will help with surgical decision making and identify patients in need for additional perioperative supports.

An examination of rectal prolapse surgery patients' quality of life and symptoms using patient-reported outcome instruments: A prospective cohort study.

BACKGROUND: We measured changes in self-reported health and symptoms attributable to rectal prolapse surgery using patient-reported outcome (PRO) measures. METHODS: A prospectively recruited cohort of patients scheduled for rectal prolapse repair in Vancouver, Canada between 2013 and 2021 were surveyed before and 6-months after surgery using seven PROs: the EuroQol Five-Dimension Instrument (EQ-5D-5L), Generalized Anxiety Disorder Scale (GAD-7), Pain Intensity, Interference with Enjoyment of Life and General Activity (PEG), Patient Health Questionnaire (PHQ-9), Fecal Incontinence Severity Index (FISI), Gastrointestinal Quality of Life Index (GIQLI), and the Fecal Incontinence Quality of Life Scale (FIQL). RESULTS: We included 46 participants who reported improvements in health status (EQ-5D-5L; p â€‹< â€‹0.01), pain interference (PEG; p â€‹< â€‹0.01), depressive symptoms (PHQ-9; p â€‹= â€‹0.01), fecal incontinence severity (FISI; p â€‹< â€‹0.01), gastrointestinal quality of life (GIQLI; p â€‹< â€‹0.01), and fecal incontinence quality of life (FIQL) related to lifestyle (p â€‹= â€‹0.02), coping and behaviour (p â€‹= â€‹0.02) and depression and self-perception (p â€‹= â€‹0.01). CONCLUSION: Surgical repair of rectal prolapse improved patients' quality of life with meaningful improvements in fecal incontinence severity and pain, and symptom interference with daily activities.

Shared Decision Making in Hallux Valgus Surgery: A Prospective Observational Study.

Patient-physician communication has the potential to improve outcomes and satisfaction through the shared decision-making process (SDM). This study aims to assess the relationship between perception of SDM and demographic, clinical, and patient-reported outcomes in patients undergoing Hallux Valgus (HV) correction. A prospective analysis of 306 patients scheduled for HV surgery was completed. The CollaboRATE score was used to measure SDM. Multivariable linear regression model was used to assess whether SDM scores were associated with preoperative characteristics or postoperative outcome scores. The mean CollaboRATE score was 2.9 (SD 0.9) and did not differ by age, socioeconomic status, or sex. Lower CollaboRATE scores were associated with more symptoms of depression, lower socioeconomic status, and lower general health scores (p-value < 0.05). There was no association between SDM scores and postoperative outcome scores. In this study, patients with depressive symptoms and lower socioeconomic status had worse perceptions of SDM. There was no difference in postoperative outcomes among participants based on SDM scores. Level of Evidence: Level III, prospective observational study.

Preparing for colorectal surgery: a feasibility study of a novel web-based multimodal prehabilitation programme in Western Canada.

AIM: Prehabilitation for colorectal cancer has focused on exercise-based interventions that are typically designed by clinicians; however, no research has yet been patient-oriented. The aim of this feasibility study was to test a web-based multimodal prehabilitation intervention (known as PREP prehab) consisting of four components (physical activity, diet, smoking cessation, psychological support) co-designed with five patient partners. METHOD: A longitudinal, two-armed (website without or with coaching support) feasibility study of 33 patients scheduled for colorectal surgery 2 weeks or more from consent (January-September 2021) in the province of British Columbia, Canada. Descriptive statistics analysed a health-related quality of life questionnaire (EQ5D-5L) at baseline (n = 25) and 3 months postsurgery (n = 21), and a follow-up patient satisfaction survey to determine the acceptability, practicality, demand for and potential efficacy in improving overall health. RESULTS: Patients had a mean age of 52 years (SD 14 years), 52% were female and they had a mean body mass index of 25 kg m-2 (SD 3.8 kg m-2). Only six patients received a Subjective Global Assessment for being at risk for malnutrition, with three classified as 'severely/moderately' malnourished. The majority (86%) of patients intended to use the prehabilitation website, and nearly three-quarters (71%) visited the website while waiting for surgery. The majority (76%) reported that information, tools and resources provided appropriate support, and 76% indicated they would recommend the PREP prehab programme. About three-quarters (76%) reported setting goals for lifestyle modification: 86% set healthy eating goals, 81% aimed to stay active and 57% sought to reduce stress once a week or more. No patients contacted the team to obtain health coaching, despite broad interest (71%) in receiving active support and 14% reporting they received 'active support'. CONCLUSION: This web-based multimodal prehabilitation programme was acceptable, practical and well-received by all colorectal surgery patients who viewed the patient-oriented multimodal website. The feasibility of providing active health coaching support requires further investigation.

Population-Based Trends in Complexity of Hospital Inpatients.

Importance: Clinical experience suggests that hospital inpatients have become more complex over time, but few studies have evaluated this impression. Objective: To assess whether there has been an increase in measures of hospital inpatient complexity over a 15-year period. Design, Setting and Participants: This cohort study used population-based administrative health data from nonelective hospitalizations from April 1, 2002, to January 31, 2017, to describe trends in the complexity of inpatients in British Columbia, Canada. Hospitalizations were included for individuals 18 years and older and for which the most responsible diagnosis did not correspond to pregnancy, childbirth, the puerperal period, or the perinatal period. Data analysis was performed from July to November 2023. Exposure: The passage of time (15-year study interval). Main Outcomes and Measures: Measures of complexity included patient characteristics at the time of admission (eg, advanced age, multimorbidity, polypharmacy, recent hospitalization), features of the index hospitalization (eg, admission via the emergency department, multiple acute medical problems, use of intensive care, prolonged length of stay, in-hospital adverse events, in-hospital death), and 30-day outcomes after hospital discharge (eg, unplanned readmission, all-cause mortality). Logistic regression was used to estimate the relative change in each measure of complexity over the entire 15-year study interval. Results: The final study cohort included 3 367 463 nonelective acute care hospital admissions occurring among 1 272 444 unique individuals (median [IQR] age, 66 [48-79] years; 49.1% female and 50.8% male individuals). Relative to the beginning of the study interval, inpatients at the end of the study interval were more likely to have been admitted via the emergency department (odds ratio [OR], 2.74; 95% CI, 2.71-2.77), to have multimorbidity (OR, 1.50; 95% CI, 1.47-1.53) and polypharmacy (OR, 1.82; 95% CI, 1.78-1.85) at presentation, to receive treatment for 5 or more acute medical issues (OR, 2.06; 95% CI, 2.02-2.09), and to experience an in-hospital adverse event (OR, 1.20; 95% CI, 1.19-1.22). The likelihood of an intensive care unit stay and of in-hospital death declined over the study interval (OR, 0.96; 95% CI, 0.95-0.97, and OR, 0.81; 95% CI, 0.80-0.83, respectively), but the risks of unplanned readmission and death in the 30 days after discharge increased (OR, 1.14; 95% CI, 1.12-1.16, and OR, 1.28; 95% CI, 1.25-1.31, respectively). Conclusions and Relevance: By most measures, hospital inpatients have become more complex over time. Health system planning should account for these trends.

Association between anesthesia technique and death after hip fracture repair for patients with COVID-19.

PURPOSE: Patients with COVID-19 undergoing hip fracture surgeries have a 30-day mortality of up to 34%. We aimed to evaluate the association between anesthesia technique and 30-day mortality after hip fracture surgery in patients with COVID-19. METHODS: After ethics approval, we performed a retrospective cohort analysis of the American College of Surgeons National Surgical Quality Improvement Program data set from January to December 2021. Inclusion criteria were age ≥ 19 yr, laboratory-confirmed SARS-CoV-2 infection within 14 days preoperatively, and hip fracture surgery under general anesthesia (GA) or spinal anesthesia (SA). Exclusion criteria were American Society of Anesthesiologists Physical Status V, ventilator dependence, international normalized ratio ≥ 1.5, partial thromboplastin time > 35 sec, and platelet count < 80 × 109 L-1. The primary outcome was all-cause 30-day mortality. The adjusted association between anesthetic technique and 30-day mortality was analyzed using multivariable logistic regression. RESULTS: Of 23,045 patients undergoing hip fracture surgery, 331 patients met the study criteria. The median [interquartile range] age was 82 [74-88] yr, and 32.3% were male. The 30-day mortality rate was 10.0% (33/331) for the cohort (10.7%, 29/272 for GA vs 6.8%, 4/59 for SA; P = 0.51; standardized mean difference, 0.138). The use of SA, compared with GA, was not associated with decreased mortality (adjusted odds ratio, 0.61; 95% confidence interval, 0.21 to 1.8; E-value, 2.49). CONCLUSION: Anesthesia technique was not associated with mortality in patients with COVID-19 undergoing hip fracture surgery. The findings were limited by a small sample size.

RéSUMé: OBJECTIF: Les personnes atteintes de COVID-19 bénéficiant d'une chirurgie de fracture de la hanche ont une mortalité à 30 jours allant jusqu'à 34 %. Notre objectif était d'évaluer l'association entre la technique d'anesthésie et la mortalité à 30 jours après une chirurgie de fracture de la hanche chez les personnes atteintes de COVID-19. MéTHODE: Après l'approbation du comité d'éthique, nous avons réalisé une analyse de cohorte rétrospective de l'ensemble de données du Programme national d'amélioration de la qualité chirurgicale de l'American College of Surgeons de janvier à décembre 2021. Les critères d'inclusion étaient un âge ≥ 19 ans, une infection par le SRAS-CoV-2 confirmée en laboratoire dans les 14 jours préopératoires et une chirurgie de fracture de la hanche sous anesthésie générale (AG) ou rachianesthésie (RA). Les critères d'exclusion étaient un statut physique V selon l'American Society of Anesthesiologists, la dépendance à une assistance ventilatoire, un ratio international normalisé ≥ 1,5, un temps de thromboplastine partielle > 35 sec, et une numération plaquettaire < 80 × 109 L−1. Le critère d'évaluation principal était la mortalité à 30 jours toutes causes confondues. L'association ajustée entre la technique anesthésique et la mortalité à 30 jours a été analysée à l'aide d'une régression logistique multivariée. RéSULTATS: Sur 23 045 patient·es opéré·es pour une fracture de la hanche, 331 répondaient aux critères de l'étude. L'âge médian (écart interquartile) était de 82 [74­88] ans et 32,3 % étaient des hommes. Le taux de mortalité à 30 jours était de 10,0 % (33/331) pour la cohorte (10,7 %, 29/272 pour l'AG vs 6,8 %, 4/59 pour la RA; P = 0,51; différence moyenne standardisée, 0,138). L'utilisation de la RA, par rapport à l'AG, n'a pas été associée à une diminution de la mortalité (rapport de cotes ajusté, 0,61; intervalle de confiance à 95 %, 0,21 à 1,8; valeur E, 2,49). CONCLUSION: La technique d'anesthésie n'a pas été associée à la mortalité chez les personnes atteintes de COVID-19 bénéficiant d'une chirurgie de fracture de la hanche. Les résultats ont été limités par la petite taille de l'échantillon. ENREGISTREMENT DE L'éTUDE: www.ClinicalTrials.gov (NCT05133648); enregistrée le 24 novembre 2021.

Federal and Provincial Governments Need To Be Transparent about Trade-Offs When They Buy Healthcare.

Spending on healthcare is carefully scrutinized by the public, the media and academics because the amounts are so large and represent a very significant proportion of provincial budgets. Some quarters are calling for increases in spending, whereas others are focused on restraint owing to perceived inefficiencies and ineffectiveness. The debate over healthcare spending has continued for decades and is likely to heat up as new provincial labour agreements have locked in annual healthcare spending increases of at least five percent for 2023 (BC Nurses' Union 2023; ONA 2023).

The Tangled Web of Integrating Health and Social Services in Canada.

It is important to have all the pieces of health and social care systems working together to maintain and improve the lives and well-being of medically complex Canadians. Being medically complex means needing physical and mental healthcare for chronic conditions, addressing functional health limitations and adapting models of care to social vulnerabilities, such as rurality or cultural safety. This could happen to any of us or to our family members, at any time.

Toward Comprehensive Care Integration in Canada: Delphi Process Findings from Researchers, Clinicians, Patients and Decision Makers.

Introduction: From a larger study examining policy and program information on how Canadian provinces integrate care services, this study aimed to create "priority lists" of 10-15 services that are "absolutely needed" for care integration. Methodology: A diverse group of over 50 Canadian stakeholders participated in virtual consensus-building using the nominal group technique and a modified e-Delphi method to identify services that focused on two different groups: children and youth with high functional health needs and older adults in functional decline. Results: Three lists - containing services, processes and infrastructure elements - emerged: one per tracer condition group and a consolidated list. The latter identified the following five services as top priority for primary care integration: mental health and addictions services; home care; transition between urgent-emergency-acute care; medication reconciliation in community pharmacies; and respite care. No single social service was a clear priority, but those that mitigate material deprivation emerged within the top 10. Discussion: This humble pan-Canadian study shows that priority services in health and social services are neither well integrated nor connected to primary care. It also suggests that effective policy strategizing for primary care integration for those with complex care needs may require thinking beyond the logic of services - given their siloed organization.

Improving the quality of care of Canadians waiting for elective surgery: an important health care priority.

The backlog of cases on surgical wait lists is a substantial problem for surgical patients, their families, surgeons, health care systems and governments. There are several approaches governments can take to improve the health, well-being and surgical outcomes of waiting patients. First, provinces should consider patient-centred approaches to triaging that reflect pain, symptoms or functional gain, and approaches using multidisciplinary teams or centralized triage. Second, governments could provide prehabilitation and mental health supports aligned with patients' and families' preferences during unavoidable waits. Wait times are not going to shorten any time soon; provinces should not only find innovative approaches to reducing waits, but also organize services to improve the health and well-being of waiting patients. Such changes will allow for optimization of patients' surgical outcomes and reduce the complexity of managing the wait list for their surgeons.

Reversing the Stigma around Canada's Poor-Performing Healthcare Systems.

Recent statistics report that healthcare spending growth is persistently high; in recent years, spending growth exceeded 5% (CIHI 2022). Some portion of the outsized growth can be attributed to the COVID-19 pandemic, though the cause is irrelevant. High spending growth in the healthcare sector is not a good prospect for taxpayers or for education and social programs competing for the same pot of money. Spending is important, but it is not the only attribute for measuring the success of our provinces' and territories' efforts to fund healthcare services that maintain or improve their populations' health.

A Problem of Money and Health: The Need for Value in Healthcare.

Almost ten years ago, on june 5, 2013, jeffrey simpson of the globe and mail wrote that more money was not the answer to reducing wait times for elective surgery (Simpson 2013). The editorial's text described the billions that had been spent by provinces through the federal Wait Times Reduction Fund to supply more surgeries and that meaningful progress on surgical wait times was still lacking.

Factors associated with frequent high-cost individuals with cystic fibrosis and their healthcare utilization and cost patterns.

Cystic fibrosis (CF) is a progressive multi-organ disease with significant morbidity placing extensive demands on the healthcare system. Little is known about those individuals with CF who continually incur high costs over multiple years. Understanding their characteristics may help inform opportunities to improve management and care, and potentially reduce costs. The purpose of this study was to identify and understand the clinical and demographic attributes of frequent high-costing CF individuals and characterize their healthcare utilization and costs over time. A longitudinal study of retrospective data was completed in British Columbia, Canada by linking the Canadian CF Registry with provincial healthcare administrative databases for the period between 2009 and 2017. Multivariable Cox regression models were employed to identify baseline factors associated with becoming a frequent high-cost CF user (vs. not a frequent high-cost CF user) in the follow-up period. We found that severe lung impairment (Hazard Ratio [HR]: 3.71, 95% confidence interval [CI], 1.49-9.21), lung transplantation (HR: 4.23, 95% CI, 1.68-10.69), liver cirrhosis with portal hypertension (HR: 10.96, 95% CI: 3.85-31.20) and female sex (HR: 1.97, 95% CI: 1.13-3.44) were associated with becoming a frequent high-cost CF user. Fifty-nine (17% of cohort) frequent high-cost CF users accounted for more than one-third of the overall total healthcare costs, largely due to inpatient hospitalization and outpatient medication costs.

Case mix-based changes in health status: A prospective study of elective surgery patients in Vancouver, Canada.

INTRODUCTION: Hospital activity is often measured using diagnosis-related groups, or case mix groups, but this information does not represent important aspects of patients' health outcomes. This study reports on case mix-based changes in health status of elective (planned) surgery patients in Vancouver, Canada. DATA AND METHODS: We used a prospectively recruited cohort of consecutive patients scheduled for planned inpatient or outpatient surgery in six acute care hospitals in Vancouver. All participants completed the EQ-5D(5L) preoperatively and 6 months postoperatively, collected from October 2015 to September 2020 and linked with hospital discharge data. The main outcome was whether patients' self-reported health status improved among different inpatient and outpatient case mix groups. RESULTS: The study included 1665 participants with completed EQ-5D(5L) preoperatively and postoperatively, representing a 44.8% participation rate across eight inpatient and outpatient surgical case mix categories. All case mix categories were associated with a statistically significant gain in health status (p < .01 or lower) as measured by the utility value and visual analogue scale score. Foot and ankle surgery patients had the lowest preoperative health status (mean utility value: 0.6103), while bariatric surgery patients reported the largest improvements in health status (mean gain in utility value: 0.1515). CONCLUSIONS: This study provides evidence that it was feasible to compare patient-reported outcomes across case mix categories of surgical patients in a consistent manner across a system of hospitals in one province in Canada. Reporting changes in health status of operative case mix categories identifies characteristics of patients more likely to experience significant gains in health.

Patient-reported mental health and well-being trajectories in oncology patients during radiation therapy: an exploratory retrospective cohort analysis using the Ontario Cancer Registry.

PURPOSE: Mental health and well-being trajectories are not expected to be homogeneous in diverse clinical populations. This exploratory study aims to identify subgroups of patients with cancer receiving radiation therapy who have different mental health and well-being trajectories, and examine which socio-demographic, physical symptoms, and clinical variables are associated with such trajectories. METHODS: Retrospective analysis of radiation therapy patients diagnosed with cancer in 2017 was conducted using data from the Ontario Cancer Registry (Canada) and linked with administrative health data. Mental health and well-being were measured using items from the Edmonton Symptom Assessment System-revised questionnaire. Patients completed up to 6 repeated measurements. We used latent class growth mixture models to identify heterogeneous mental health trajectories of anxiety, depression, and well-being. Bivariate multinomial logistic regressions were conducted to explore variables associated with the latent classes (subgroups). RESULTS: The cohort (N = 3416) with a mean age of 64.5 years consisted of 51.7% females. Respiratory cancer was the most common diagnosis (30.4%) with moderate to severe comorbidity burden. Four latent classes with distinct anxiety, depression, and well-being trajectories were identified. Decreasing mental health and well-being trajectories are associated with being female; living in neighborhoods with lower income, greater population density, and higher proportion of foreign-born individuals; and having higher comorbidity burden. CONCLUSIONS: The findings highlight the importance of considering social determinants of mental health and well-being, in addition to symptoms and clinical variables, when providing care for patients undergoing radiation therapy.

Associations between perceptions of shared decision making and health among hysterectomy patients: A prospective observational study.

OBJECTIVE: To investigate patient and clinical factors that are associated with perceptions of shared decision making between hysterectomy patients and surgeons and to evaluate associations between shared decision making and postoperative health. METHODS: This study is based on a prospective cohort scheduled for hysterectomy for benign conditions in Vancouver, Canada. Validated patient-reported outcomes assessed shared decision making, pelvic health, depression, and pain. Regression analyses measured the association between perceptions of shared decision making with patient and clinical factors. Then, associations between shared decision making with postoperative pelvic health, pain and depression were evaluated using regression analysis and adjusted for patient and clinical factors. RESULTS: In this study, 308 participants completed preoperative measures, and a subset of 146 participants also completed the postoperative measures. More than 50% of participants reported less than optimal shared decision making scores. No significant associations were identified between patients' perceptions of shared decision making with patients' age, comorbidities, socioeconomic factors, indication for surgery, or preoperative depression and pain. Regression analyses found that higher/better self-reported shared decision making scores were associated with fewer postoperative pelvic organ symptoms (P = 0.01). CONCLUSION: Many patients' reporting lower than optimal scores on the shared decision making instrument highlight the opportunity to improve surgeon-patient communication in this surgical cohort. Strengthening shared decision making between surgeons and their patients may be associated with improved self-reported postoperative health.

Associations between clinical pathway concordance, cost, and survival outcomes for stage II colon cancer: a population-based study.

This study measures patient's concordance between clinical reference pathways with survival or cost among a population-based cohort of colon cancer patients applying a continuous measure of concordance. The primary hypothesis is that a higher concordance score with the clinical pathway is significantly associated with longer survival or lower cost. The study informs whether patient's adherence to a defined clinical pathway is beneficial to patients' outcomes or health system. An externally determined clinical pathway for colon cancer was used to identify treatment nodes in colon cancer care. Using observational data up to 2019, the study generated a continuous measure of pathway concordance. The study measured whether incremental improvements in pathway concordance were associated with survival and treatment costs. Concordance between patients' reference pathways and their observed trajectories of care was highly statistically associated with survivorship [hazard ratio: 0.95 (95% confidence interval, CI, 0.95-0.96)], showing that adherence to the clinical pathway was associated with a lower mortality rate. An increase in concordance was statistically significantly associated with a decrease in health system cost. When patients' care followed the clinical pathway, survival outcomes were better and total health system costs were lower in this cohort. This finding creates a compelling case for further research into understanding the barriers to pathway concordance and developing interventions to improve outcomes and help providers implement best practice care where appropriate.
